What is the cut out speed of Kestrel’s wind turbines?
-
There is no cut-out wind speed. The e160i, e230i, e300i, e400n are designed to produce full power in any wind above 12m/s.
The e230i, e300i and e400n models are fitted with a patented pitch control. Blade pitch control is the system which monitors and adjusts the inclination angle of the blades and thus controls the rotation speed of the blades. At lower wind speeds, the pitching system leads to an acceleration of the hub rotation speed, while at higher speeds, blade pitch control reduces the wind load on the blades and structure of the turbine.

What would you use renewable energy for?
-
Renewable energy can be used in different applications:
- Off grid systems: used in locations where the national grid is not available e.g. farms and rural communities (view/download the off grid brochure)
- Grid connected systems: used to supplement grid power e.g. domestic and commercial use
(view/download the grid connected brochure)
- Water pumping systems: used to move water e.g. from a borehole to a reservoir

Is a renewable energy system suitable for my home?
-
Different off-grid and grid connected systems has been installed at homes across the globe. A few things to consider when installing a renewable energy system at your home:
- Your location is very important when you are considering installing a renewable energy system.
- There must be no significant nearby obstructions like trees or buildings on your property as these are likely to reduce wind speed and increase turbulence.
- System installation normally requires permission from the local authority, so it's important to always check with your local authority about planning issues before you have a system installed.
- An EIA (Environmental Impact Assessment) is needed when installing a turbine of 15 metres or higher.
